Researchers at the City University of New York (CUNY) Energy Institute at City College are buying those AA batteries off the shelf for research on large-scale batteries.
Those alkaline batteries that are cheap and energy dense, for one-time usage only? As it turns out, the first 2 properties are useful for large-scale storage too. As for alkaline batteries that are one-time use only, it may not be so simple. The researchers found that if the batteries are not fully depleted, they are capable of recharging.
Furthermore, metals used to build such batteries, namely zinc and manganese, are abundant and cheap.
One problem that has to be overcome with batteries is the degradation over time, and the scientists have to understand their irregularities in order to make the batteries more sustainable.
If you want to know more about this and other topics directly from end users of energy storage technologies join us at one of these annual events: The Energy Storage World Forum (Grid Scale Applications), or The Residential Energy Storage Forum, or one of our Training Courses.
